Top SchoolHerman Semykozov is a Lead Engineer based in Tallinn with 11 years of experience building front-end systems and design-driven UI kits, currently leading billing and UI-kit teams at 3Commas. He specializes in React, TypeScript, Storybook and design-systems, pairing design tools like Figma with robust engineering practices (storybook-driven components, CSS-in-JS, atomic design).

He’s practiced at maturing team processes (agile rituals, 1:1s, code review) and shipping high-load products and PWAs across fintech and crypto domains. Outside his day job he maintains notable side projects (learn.javascript.info, flowquiz.com) that reflect a commitment to developer education and practical tooling.
